What are the things your parents did that you will never do to your kids or future kids?

Caning. My parents used to chase my brother and I around with a cane to beat us whenever we misbehave or used to threaten us. I feel it isn't very effective because it's just cultivating fear. Once the kid grow old, this fear disappears. So I went with respectful parenting instead, constantly talking to my kid, have a 2 way communication and teach him to have respect for one another. It's a long term solution I guess.
